PHP电子邮件表单未提交[关闭]

Question

好的，所以我已经四处寻找这个特定的问题，但我找不到它，所以我希望这不是重复。

因此，我使用链接到本地​​主机上的“html_form_send.php”的“/contacts.html”页面设置了一个联系人表单。一旦用户按下“提交”，此消息就会出现在下一页：

“非常抱歉，您提交的表单存在错误。这些错误显示在下方。

很抱歉，您提交的表单似乎有问题。

请返回并修复这些错误。”

无论您是否正确或错误地填写了所有字段或未填写任何字段，都会显示此消息。为什么？

    <?php
if(isset($_POST['email'])) {

    // CHANGE THE TWO LINES BELOW
    $email_to = "xxxxxxxx.yyyyyyy@gmail.com";

    $email_subject = "Quantum1Connect Contact Request";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if(!isset($_POST['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }

    $first_name = $_POST['first_name']; // required
    $last_name = $_POST['last_name']; // not required
    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['comments']; // required

    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "/^[A-Za-z .'-]+$/";
  if(!preg_match($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
  if(!preg_match($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';
  }
  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }
  if(strlen($error_message) > 0) {
    died($error_message);
  }
    $email_message = "Form details below.\n\n";

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }

    $email_message .= "First Name: ".clean_string($first_name)."\n";
    $email_message .= "Last Name: ".clean_string($last_name)."\n";
    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\n";


// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($email_to, $email_subject, $email_message, $headers);  
?>

变化：

<textarea class="contact textarea" rows="8" cols="50" name="message"></textarea>

到：

<textarea class="contact textarea" rows="8" cols="50" name="comments"></textarea>

您已将 html textarea 的名称设置为 message，但您正在测试 php 代码中名为 cmets 的 textarea。

正如@Fred-ii 指出的那样，您正在POST 中测试telephone，但html 中的值是phone

AND 删除 - 创建第二个表单的 <form action="index.php">！

顺便说一句，在 SO 中发布此问题只需花费一半的精力，即可运行一些快速调试 echo/print_r/error_reporting 语句并弄清楚这一点。如果您打算在未来进行更多的编程，我强烈建议您提高调试技能，对于这样的小问题更容易和更有效。对于更大的，总是有这样的:-)

不是愤世嫉俗，只是一个建议 :) 祝你好运！
